java - Hibernate 実行中の XML 解析エラー

Question

私は休止状態の初心者です。最初の休止状態プログラムを試してみましたが、成功しませんでした。休止状態プログラムの実行中に次のエラーが発生しました。

Exception in thread "main" org.hibernate.HibernateException: Could not parse configuration: Hibernate.cfg.xml
    at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:1586)
    at org.hibernate.cfg.Configuration.configure(Configuration.java:1520)
    at com.test.Test.main(Test.java:16)
Caused by: org.dom4j.DocumentException: Error on line 11 of document  : The content of elements must consist of well-formed character data or markup. Nested exception: The content of elements must consist of well-formed character data or markup.
    at org.dom4j.io.SAXReader.read(SAXReader.java:482)
    at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:1576)

これは休止状態の構成ファイルです。
